Abstract

En la presente invención se describe un rodillo donador para el transportede pigmento orgánico, en un sistema de revelado, para un aparato copiadorelectrofotográfico, que incluye una superficie exterior de resinafenólica. La resina se calcula para una conductividad adecuada, parafacilitar una constante de tiempo de descarga en el mismo de menos de 300microsegundos. El rodillo donador se usa en conjunción con una estructurade electrodos, como se usa en el revelado sin barrido o sin rozamiento.In the present invention, a donor roller for the transport of organic pigment, in a developing system, is described for an electrophotographic copying apparatus, which includes an outer surface of phenolic resin. The resin is calculated for a suitable conductivity, to facilitate a discharge time constant in it of less than 300microseconds. The donor roll is used in conjunction with an electrode structure, as used in developing without wiping or friction.
